In Ensemble app open the first demo - Stacked Area Chart. Turn on the voice assistant (like VoiceOver on Mac) and navigate to data points on chart using the navigation shortcuts. When voice assistant reads the element it reads (for example) X Axis is 5 Y Axis is 10 - despite the actual labels of the axis that can be edited in the demo properties.

The axis name should be provided to the a11y API instead of the predefined text.
